public abstract class LpexFieldEditorPreferencePage

extends org.eclipse.jface.preference.FieldEditorPreferencePage

implements org.eclipse.ui.IWorkbenchPreferencePage

LPEX adaptation of FieldEditorPreferencePage. It implements a series of common methods used by LPEX preference pages. Method contributeButtons() adds a "Reset" button, which restores the initial settings in effect when the preference page came up.

Eclipse's FieldEditorPreferencePage is an abstract preference page for hosting field editors. Subclasses must implement the createFieldEditors method, and should override createLayout() if a special layout of the field editors is needed.
